JOHN IV. CARTER, OF NEIVTON, MASSACHUSETTS.

STOPPER.

SPECIFIGATION forming part of Letters Patent No. 462,857, dated November10, 1891.

Application filed June 19, 1891. Serial No. 396.855- (No model.)

To all whom it may concern.-

Be it known that I, JOHN V. CARTER, a citizen of the United States,residing at Newton, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement in Stoppers,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

The stopper comprises a central spindle or core having a flange and knobor handle, made preferably integral and of glass, wood, metal, formativematerial, or any other suitable substance, and having also projectingfrom the shank barbs, preferably having flat upper surfaces, and fromthe under surface of the flange points or barbs, and a yielding sleeveor jacket, preferably of cork, forced upon said spindle and barbs andagainst said points to bring its upper edge against the lower surface ofthe flange.

In the drawings, Figure l is a view in elevation of the stopper, withthe exception of the jacket. Fig. 2 is a view in section of the stopperinverted upon the line of 00 at, Fig. 1, and in plan of parts below saidline. Fig. 3 is a view, partly in elevation and partly in section, ofthe complete stopper. Fig. & is a view representing a slight change inthe size and number of the holding-barbs. Figs. 5 and G are viewsrepresenting the points upon the flange of the stopper as made in theform of barbs.

Referring to the drawings, (t represents the core or spindle of thestopper, a the knob or handle, and a the flange. Extending from thesides of the core or spindle are the barbs b. There may be anynumber ofthem used, and preferably they each have the long or relatively-1onginclined surface I) upon its under side or side toward the lower end ofthe core or spindle and the flat or relatively-flat upper 111 thedrawings I have represented the core or spindle as having four of thesebarbs arranged lengthwise the core and quarteringlyin relation to eachother. From the under surface of the flange a there extends downward thepoints 0. I have represented two points in the drawings; but do notconfine myself to that number. I have also shown them as arranged inline with two of the barb projections, and while I prefer thisarrangement in relation to the barbs, as it is a help in the making ofmolded stopper-cores, the mold being divided upon the line of thepoints, and because they also act to force the cork or other material ofthe jacket above the barbs against the side of the spindle or core asthe core or spindle is being forced into the cork, still I do notconfine myself to this location. The core, flange, knob or handle,barbs, and points preferably are made integral, and while I prefer thatthey be formed of glass, yet I do not wish to be understood as limitingmyself to glass, as anyother suitable substance may be used for thepurpose. The jacket (Z is preferably made of cork, although notnecessarily so, as it may be made of rubber or any other resilientmaterial, and is preferably formed with the hole (1, extending from itsupper end to near its bottom, the hole preferably being somewhat smallerthan the core a, and the two parts are unit-ed by forcing the corestraight into the hole (1 until the upper surface (Z of the jacket comesinto contact with the lower surface of the flange (1. when the barbs Z2and points 0 will be pressed into the material of the jacket and thematerial closed over the flat surfaces of the barbs by its resiliencyorelasticity and also by the spreading action of the prongs c. Thisinsures that the jacket be held to the remainder of the stopper in amanner to prevent their being separated by a pulling action upon thejacket by the knob or handle or by a turning action of the knob orhandle in relation to the jacket, the barbs b acting as stops to prevent the first and the points 0 stops to prevent the seeond, and bothco-operatiug to make a very perfect union between the jacket and thecore and flange.

I do not confine the shape of the points 0 to that represented in Figs.1, 2, and 3; but may make them in the shape of barbs, as represented inFig. (3, and when so made I prefer that the barb faces oppose eachother, so that whichever way the stopper is turned there shall always bea barb face opposed to the direction of the turning movement.
